Re: how to back up data, changing mobo?
Okay, you can do this one of two ways:
1) Slave your current hard drive to the new hard drive (after you get it all set up and working, of course), and copy the files from the old to the new.
2) Slave the new hard drive to your current hard drive and, again, copy the files from the old to the new.
Either way, when you slave either drive, the BIOS should recognize it on startup without you having to do anything. A new drive letter will appear in your My Computer which will be the drive you slaved. All you have to do from there is copy and paste.
